It is composed of an analog/digital) conversion codec 25, an audio signal amplifier 26, a transformer 27, a DC cut capacitor 28, and an interface circuit 29.

The audio data sent from the audio processing unit 3 is sent to the subscriber line Lj via the audio data processing signal processor 24, the Δ/D conversion codec 25, the audio signal amplifier 26, and the transformer 27. . The two interface circuits have an interface function for output signals from the called name response signal detection circuit 22 and busy tone detection circuit 23 and control signals from the system control section 4.

The voice processing unit 3 sequentially extracts voice signal data from the voice signal data memory 30 in which prerecorded messages are converted into digital signals and stored therein, and processes the line fee W unit 2-j. The audio signal processing circuit 31 is distributed to the audio data processing signal processor 24.

The system control unit 4 includes a central processing unit 40 that controls the entire system, a main memory 41 that stores telephone number data of other parties, message data, and programs that control the central processing unit 40, and a central processing unit 40 that controls the entire system. Processing device 40

Next, with reference to FIGS. 1 and 2, the operation of an embodiment of the present invention will be described, for example, when the system is used for emergency communication between a school and a student's home. Several messages to be communicated are stored in advance in the audio signal data memory 3o, and the home contact telephone numbers of all students are registered in the main memory 41 from the console 42. When an operator wants to make an emergency notification to students in a specific class at school that the class will be closed due to a cold, or to notify students in other classes that the start time will be delayed due to a cold, the operator can The central processing unit 40 is activated by inputting the code of the relevant class and the female code of the relevant message via the .

The central processing unit 40 first activates the off-hook circuit 20 of the line control unit 2 via the interface circuit 29, and connects the corresponding subscriber line to the exchange 1i 1115 side.

to the calling state. Next, the central processing unit 40 uses the main memory 4
One of the contact telephone number data of the students in the corresponding class is taken out from 1 and sent to the dial signal sending circuit 21 via the interface circuit 29.

The dial signal sending circuit 21 converts the telephone number data into a predetermined signal of DP (dial pulse) or Pa (button button) and sends it to the subscriber line.

When the called party responds to this signal, a polarity inversion signal is sent from the exchange 5 side. When this polarity inversion signal is detected by the called name response signal detection circuit 22, the detection signal is sent to the central processing unit via the interface circuit 29. Sent to 40.

Next, the central processing unit 40 extracts vertical data information from the main memory 41 based on the vertical code of the input message to be sent and sends it to the audio signal processing circuit 31. The audio signal processing circuit 31 sequentially extracts audio signal data from the audio signal data memory 30 based on the vertical data information and distributes it to the audio data processing signal processor 24.

The audio signal data becomes an analog audio signal via the audio data processing signal processor 24 and the A/D conversion codec 25, is amplified by the audio signal amplifier 26, and is then sent to the subscriber line via the transformer 27. The message was sent out as saying, ``The class will be closed due to this.'' After a certain period of time corresponding to the time of the sent message, the central processing unit 40 disconnects the off-hook circuit 20 via the interface circuit 29, stops sending the message, and stops the call.

Next, the central processing unit 40 activates the off-hook circuit 20 again after a certain period of time to ensure recovery time on the exchange 5 side, retrieves the next contact telephone number data from the main memory 41, and sends a message in the same manner as above. Send out. When there are multiple line control units 2-j and corresponding subscriber line circuits, the central processing unit 40 controls the multiple line control units 2-j.
It is possible to send messages independently to each
Messages can be sent to multiple subscribers at the same time.

By repeating the above operations, the central processing unit 40 finishes sending messages to the phone numbers of all students in the relevant class, and then sends messages to the phone numbers of all students in other classes.
A message to the effect that "starting time will be delayed due to cold" is sent out by repeating the above-mentioned operations. Once these messages have been sent, a completion message is displayed and the operation is complete.

Incidentally, when the called party is on the line first and the called party is busy, the busy tone detection circuit 23 detects the busy tone sent from the exchange 5, and the central processing unit 40 disconnects the off-hook circuit 20. or,
If the called party does not respond, the off-hook circuit 20 is similarly disconnected after a certain period of time. These unresponsive (including busy) called names are displayed on a display device (not shown) or the like.

In this way, messages to be transmitted for each group are stored in advance, and messages corresponding to each group are sent sequentially or simultaneously to the destinations that make up the pre-stored group. It is possible to notify each group of each group at the same time without requiring manpower and time.

Furthermore, by registering subscriber telephone numbers and a plurality of messages to be sent, it is possible to economically provide a simultaneous communication system 1 that self-helply sends any registered message to any other subscriber group. The practical effect is extremely large.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, messages to be transmitted are stored in advance for each group, and messages corresponding to each group are transmitted sequentially or simultaneously to destinations constituting the pre-stored group. By transmitting the information, there is an effect that the notification items for each group can be communicated to each group at the same time without requiring manpower and time.
